How many Faraday of electricity are required to deposit 0.20 mole of nickel, if 0.10 Faraday of electricity deposited 2.98g of nickel during electrolysis of its aqueous solution?

(Ni = 58.7, 1F = 96 500 C mol-)

A
0.20
B

C
0.40
D
0.50

Correct Option: C

No of mole → (2.98)/(58.7) ..............0.1

                       2.0 .................x<br />

∴ x = (0.2)/(2.98) x 58.7 x 0.40
